Re: [Haskell-beginners] What is the Haskell idiom for "if then else if then"

http://www.haskell.org/haskellwiki/If-then-else#Replace_syntactic_sugar_by_a... mentions that there is no such function in Prelude. On Mon, Mar 30, 2009 at 11:33 AM, Peter Hickman wrote:

I've just written this piece of code

   if r < 0    then LEFT    else        if r > 0        then RIGHT        else STRAIGHT

which works just fine but it does look rather clunky (as it would in any language I suppose). Is there a Haskell idiom for this type of code?
